The Twilight star took to Instagram on Friday to share a sexy snap from her and Khoury's vacation in Hawaii, where they appeared to visit a nude beach. Greene looked away from the camera as she posed in her birthday suit, with waves -- and a couple other (clothed) beachgoers -- in the background.
'He keeps me wild and free. #nudebeach #whiteboycray #honeymoon,' she wrote alongside the pic.
